When I looked into this I found that there was nothing availabel that you could just stick int the ground and get instant results.
Soil Chemistry is complex stuff that takes a lot of expertise and a lab full of equipment to be accurate.
What I use is a place call Spectrum Analytic
They ahve the results done in 24 hours and the results can be obtianed online. They charge 8.50 for there basic test.
I would check them out.
Also, a test for nitrogen is not usually done since nitrogen is so mobile in the soil -- a test would not really give you important information.
Hope this helps
